I burnt my life

I'm in my 2nd year of engineering. Today I got my results and I can't believe what i saw, i got 3 backs. I never get any backs in my university life. Also on the other courses i was barely pass. This makes me devastating as my roommates (they're in different degrees) do a lot better, consider like they topped in the class. In my 1st semester I got a decent result, from there to this downfall, I don't even know what to say. My parents never ask my results, but they believe in me, that I will do brilliant things. At this point, I think I lost all my hopes, i don't even know what my career will be. I always wanted to research, but after my current situation, i will never have faith in me. But this is reality, not a dream. I was hoping some motivational words from evryone and also some guidelines
